zen of the United States, residing at Chicago,

in the county oiCook'and State of Illinois, haveinvented certain newand useful Imrovements in Dump-Cars, of which the iolowing is a speciication.

My-invention relates to railway cars, and

morekparticiilarly to tilting dump cars, the objectbeing to provide-an improved car of this type.

Another object of my invention is to provide a box car that can be used in an ordinary Way when desired or can be 'used as a dump car when desired.

Another'object of my invention is to rovide aside bearing that shall be securely eld in position under normal circumstances, but that may be displaced to facilitate dumping.

These and other objects of my invention will be made apparent in the following specieationand claims.l

Referring to the drawings-Figure 1 'repre-` sents a cross section lof my improved car;

and Fig. 2 isa detail showin the supporting connection between the truc frame and the car body.

The bolster 15ihas'a-,shal1ow spherical ou l 16 in the middle of its upper surfacein whic rests a correspondin Aconvex spherical member 17 attached to t e under side of a longitudinal center sill 1S. Diagonal braces '18a extend out from this center sill andsup ort the cross sills 18". At each side of the olster 15 stands aside bearin member 19 pivoted to the bolster at 20 an carrying a shoulder 21. The link 2 3-is pivoted tothe bolster at the ppint 22, and has connected to itan other link 24, the outer end of which' carriesa'pin 25 which supports the shoulder 21 when the toggle joint formed by thetwo said.

links lies fiat and extended on'vtlie bolster.. A chain 26' has its ends at,ta ched"to the ends of the bolster 15 at the pbints 27 and passes over the pulleys 2S o n the under side of tthe car body. On the saine shaft withone of `the pulleys 28 is a handle 29 with a ratchet and pawl connection 30 between it and the said pulley. On the cross sills 18b the box car 31 is supported.l It has side doors 82 pivoted alon Atheir u er edves as -shown and swinging outwardly. The convex spherical bearing member 17 has laterally extending,

Slots 17a-shown in Fig. 2. The king-bolt 29 the pulley 28 is rotated in the roper direotion and with a little start by t iis means the car tilts over and dumps through the swinging door on the opposite side. By

. means of the handle 29, the car may also be righted after dumping. When the Car goes varound a curve thel truck must of course r0- tate with reference to the carbody around a vertical axis, and when the car dumps; there .must be relative rotation around the longitudinal axis. The joint illustrated in. Fig. 2 obviously permits both of these movements..

I claim: A.1. A car comprising a truck, a car bodyl ivotally mounted thereon so as to permit v ateral tilting, side bearing members iixed on the car body, and res ectively opposed side bearing members on t e truck, the latter being pivoted to the truck and having shoulders with co-acting stops to hold them in place when desired.

2. A side bearing for a tilting dump car,

vcomprising two opposed bearing members,

one of them being pivotally mounted and havinga shoulder, and a stop'co-acting with vthe shoulder.

a universal jointbetween each of said trucks,

and said'car body, side bearings mounted on said trucks, stopson said side bearings, members mounted on the trucks and coacting withsaid stops, means whereby said members can be disengaged from said stops, and means for tilting the car body. p

A,5. A car body, a center sill, transverse beams aboveand resting on said center sill,

pulley.

said center sill eonstituting` the sole supportl comprising ,a bearing member fixed on the ing means of said ear body, two trucks, universal joints between said trucks and center sill, side bearings mounted on said trucks, means for moving said side bearings into and out of engagement with said car body, and mea-ns for tilting the ear body.

6. A car having a pivotal support on a truck, so as to permit lateral tilting, a chain With its ends attached at the sides of the truck and passing over a pulley .on the car body, and controlling means attached to the 7. A eer having a pivotal support on a truck so as to permit lateral tilting, a chain With its ends attached at the sides of the truck and passing over a pulley on the ear body, and a handle attached by a ratchet and pawl connection to the pulley.

8. A side bearing for a tilting dump car,

car body, an opposedbearing member pivoted on the truck, a shoulder on the lastnamed member, a stop adapted to engage the shoulder, said stop being on the end of a link which is pivoted to another link Whichin turn is pivoted to the truck frame so that the two links lie vflat and extended on the truck frame when the stop engages the shoulder.

' 9. A car having a pivotal support on a truck so as to permit lateral tilting, a chain with its ends attached at the sides of the truck and passing over a pulley on the car body, means attached to the pulley for ro tating it, and means for holding it in any desired position.
